First of all, 'impose' is a poor choice in words. I'm not talking about *imposing* beliefs. I could reverse the question and ask who, besides Muslim radicals are we trying to *impose* our beliefs on? I was addressing the repect of beliefs and opinion.
To answer your question with regards to beliefs and opinions, and who tries to 'push' theirs and/or disregard/disrespect ours ....France, Germany, Spain, Italy, China, Russia, India, Canada, Mexico, Venezuela etc., etc., etc. Watching the news or reading print media or Internet media I am constantly coming across 'someone', from 'somewhere' ranting about the US and how we should do this or we should do that, or we should have done this or that, or we screwed something up or botched this or that, or we need to act one way or another. Just listen to some of the discourse in the UN on any given day.
It is very popular these days to 'lecture' or even put down the US. It is widely used by politicians in other countries to gain popularity and/or 'brownie points' with constituants. We get everything from polite disagreement to red-faced, flag burning rants.
But, for some reason when we (the USA) are critical, express dissatisfaction, give an opinion, or clash beliefs people seem to get indignant. How dare we have anything to say! It frustrates me.
I'm not attacking you, I'm just expresing my frustration and my opinion.
